spinning pots after precipitation of the yarn.

Such a cake is usually supported axially only by a soft knitted tube and forms a cy n wall of substantial length and thickness whose ends tend to taper and are of lesser firmness and density and of greater expansibility than the intermediate portion of the cake. When dyes are forced radially through the walls of such cylinders in opposite directions in the usual manner, the yarn sections adjacent to the ends of the cake frequently fail to absorb the dyestuff uniformly with the remainder of the cake, thereby producing off-shade sections of yarn.

Our apparatus overcomes this difliculty by forcing the dyestuff axially or diagonally as well as radially through the cake while the ends thereof are confined or compacted and held against expansion and escape of the dyestuff radially from the end sections is prevented.

In carrying out our invention, the cake is mounted on a frusto-conical spool composed of separable sections each comprising a conical tube having an arcuately flared end and a flange of substantially L-shaped cross section integral therewith and providing the spool with axially extendingspaced rims partially overlapping but radially spaced from the tubular portion of the spool. The tubular, arcuate, and, if desired, radial portions of the spool are provided with closely arranged small ports through which the dyeing fluid is jetted into a cake telescoped on the spool.

The end portions of the cake are confined and compacted between the arcuate sections and inturned rim sections of the spool and jets of dye fluid are injected in intersecting directions into these confined portions of the cake and the direct radial escape of dye fluid therefrom is prevented by the jntumed rims.

The ports also drain dyeing fluid from the cake when dye fluid is applied exteriorly thereto.

The characteristic features and advantages of our improvements will further appear from the following description and the accompanying drawings in illustration thereof.

In the drawings, Fig. 1 is a somewhat diagrammatic part sectional view of dyeing apparatus embodying our invention; Fig. 2 is an enlarged fragmentary part sectional view of the improved spools embodied in our invention mounted on a supply shaft; Fig. 3 is a further enlarged view of one of the spools, with parts broken away; Fig. 4 is a fragmentary end view of the spool shown in Fig. 3; Fig. 5 is a transverse sectional view on the line 55 of Fig. 2; and Fig. 6 is a sectional view of a portion of a spool taken on the line 6-5 of Fig. 3.

In the embodiment of our invention illustrated in the drawings, a pressure drum I has an open end adapted to be sealed by a detachable head 2 which may be connected with the drum by any suitable means, as, for instance, the bolts 3, the joint being sealed by a gasket 4. A pipe 5 is mounted in the fixed head 6 and diaphragm 1 o: the drum and supports a shaft 1', Fig. 5, having a plurality of radial webs or spokes 8, theends of which are welded to the circumference of the pipe 5 adjacent to the flange or disk 9 thereon.

A series of spools I0 are sleeved on the webs 8 of the shaft and may be held against axial movement thereon by a disk ll sleeved on the threaded stud l2 on the outer end of the shaft 1 and held in place by a thumb nut i3 screwed on said stud l2.

Each spool I0 is composed of a complementary pair of similar members having annular ends abutting along the line I, Fig. 3, and making a close slip fit adjacent to such line with the quintuplet webs 8 which form triangular channels l5 extending parallel with the axis of the shaft 1 and of the spools l0.

Each of the complementary spool members comprises a frusto-conical tubular shaft section l5 tapering gradually outward from the line of abutment It to a head comprising an arcuately flared section l6 from which projects a radial flange ll having an overturned edge forming a rim l8. The rim I8 is radially spaced from the arcuate section l6 and extends axially toward the line of juncture ll.

The shaft sections 15 and head sections iii of each spool contain the preferably countersunk apertures l9 and 20, the latter of which may be extended out radially to any desired degree on the flanges II, but preferably a section of the flange ll adjacent to the rim i3 is left imperforate so that when the heads of adjacent spools are abutted together on the shaft I, there is a relatively tight joint formed between the heads adjacent to the peripheries thereof.

The countersunk apertures l9 extend substantially radially to the axis of the spools, whereas the countersunk apertures 20 extend diagonally to or substantially parallel with such axis so that jets ejected through the several apertures take intersecting directions.

The distance between the complementary flanges ll of a spool is substantially equal to the axial length of a cake of yarn A when the edges of such cake are in normally compacted condition, and the inner diameter of each rim I8 is substantially equal to the outside diameter of the end of a yarn cake when the strands thereof are in normally compacted condition. Hence when a-yam cake sheathed in its usual stockinet tubular casing is telescoped on the complementary members of a spool and the abutting edges of the latter are brought together, the yarn cake is held in substantially the form in which it was wound in the spinning pot. A series of spools with yarn cakes telescoped thereon are sleeved on the shaft 1' and the juxtaposed edges of the complementary members of each spool and the radial edges of the heads of adjacent spools are clamped tightly together on the shaft between the disks 9 and H by tightening u the thumb screw I3. The tapering and arcuate contour of the members of juxtaposed spools form chambers 2| to which or from which dye flows through the channels l5.

Dyeing fluid may be supplied under pressure and in alternation to the interior and exterior of the yarn cakes on the spools ill in any suitable manner, as, for instance, by a force pump 22 fed from a dye vat 23 and discharging through a conduit 24 to the valved pipe 5 communicating with the channels I5 or discharging through the valved pipe 25 to the pressure tank I exteriorly f the spools ID. A valved return pipe 26 connects the top of the pressure drum I with the open 'dye vat 23. The return pipe 26 is also connected with the pipe through the valved by-pass 21'and with the pipe 24 through the valved by-pass' 28.

In the practice of our invention, dye is pumped under pressure through the pipes 24 and 25 into the channels IS, the valves of the pipes 25 and 28 being closed and the valve of the return pipe 26 open. The pressure of the dye liquid in the channels l5 forces jets of dye liquid through the apertures i 9 and into cakes A in intersecting directions and the end portions of the cakes A are held against distension and confined to substantially the same density as the intermediate portion of the cakes by the flanges I8 which prevent the radial escape of the dye from the ends of the cakes and require it to follow an axial course through the ends of the cakes before it can escape radially from the intermediate portions of said cakes. The eiiluent from the cakes is discharged from the pressure chamber I through the valved return pipe 26 to the vat 23. The-retum flow is so controlled as to maintain a desired pressure in the tank I.

When the dye fluid has flowed from the inside to the outside of the cakes A for a desired period, the valves in the pipes 5, 26 and 28 are closed and the valves in the pipes and 21 are opened. whereupon the pump 22 pumps dye liquid through the pipe 25 into the pressure tank I whence it flows through the cakes A reversely to its previous direction of flow and escapes from said cakes through the ports l9 and 20, channels l6, pipes 5. 21 and 28, back to the dye vat 23; the desired pressure in the chamber I being controlled by regulating the valve in the pipe 21.

By our improved apparatus we obtain uniform dyeing of the entire yarn cake expeditiously and economically.

1. In dyeing apparatus including a shaft memberhaving webs defining interveninglongitudinal fluid channels, the combination of end abutting complemental spool components on said shaft, each such spool embodying a frusto-conical tubular section having a flaring end on its inner tubular surface bounding a fluid channel between them, said flaring end terminating in a substantially radial flange, and said flanges havmg peripheral portions jointly forming a-substantially tight joint for such fluid channel.
